  1. Fix crashes caused by improper error handling for bpf_*_elem 

    bpf_*_elem returns -errno when error occured. These functions will
return -ENOENT(-2) when they failed to find a entry. It's a harmless
error that could be found when doing delete and print/zero/clear
operations on the same map simultaneously. It's not reasonable to
stop the whole program at this moment.
